摘　　要：本文针对破冰船破冰作业时的船体结构振动开展了实船试验研究,分析了船舶破冰总振动及局部振动特性,探索了船舶破冰振动沿船长及上层建筑方向的分布规律,并将其与船舶振动衡准进行了对比。研究表明,船舶破冰作业时会产生较大振动,引起船体的总振动及局部振动响应,且船舶局部振动与破冰载荷作用位置及船体板架固有频率密切相关;船舶破冰振动的影响主要集中于艏部冰带作用区域,并沿船长及上层建筑方向逐渐递减;破冰作业时会对船上适居性产生影响,且对不同区域的影响差异较大。Regarding the problem of hull structural vibration caused by icebreaking,the full-scale test has been carried out on an icebreaker.The characteristic of overall and local vibration of the hull caused by ice⁃breaking force was analyzed.The law of vibration acceleration distributed along the hull longitudinal direc⁃tion as well as vertical direction was explored and compared with vibration evaluation standard of new ISO 6954.The results suggest that both the overall and local vibrations occur during the icebreaking,there is close relation between the local hull vibration and the region of icebreaking force as well as natural frequency of hull stiffened plates.The incidence of icebreaking force is mainly on the bow,and the effect will gradually declines along hull longitudinal and vertical direction.The habitability is also influenced during icebreaking,and the effect is different among different areas on the icebreaker.
